Abstract:
Objective To explore the effects of lower esophageal leiomyoma on esophageal dynamics.Methods A total of 25 patients with lower esophageal leiomyoma,31 patients with gastroesophageal reflux disease (GERD) and 16 healthy controls were selected.The differences of high resolution esophageal manometry results were compared among the groups.The t-test or one way analysis of variance was performed for normally distributed measurement data comparison.Rank sum test was used for non-normally distributed measurement data comparison.Results Among 25 patients with lower esophageal leiomyoma,14 patients accompanied with acid reflux,heartburn,chest pain or other GERD symptoms.In the group of patients with lower esophageal leiomyoma,the lower esophageal sphincter pressure (LESP),the lower esophageal sphincter relaxation rate (LESRR),low esophageal body pressure and peristaltic contraction percentage were (9.00 ± 6.30) mmHg (1 mmHg =0.133 kPa),53.0 ％ (0,334.0％),(34.66±18.33) mmHg and 55.6％ (0,100.0％),respectively,which were lower than those of the healthy control group ((16.25 ± 3.71) mmHg,86.5％ (49.0％,103.0％),(57.75 ± 22.49) mmHg,100.0％ (80.0％,100.0％)),and the differences were statistically significant (t=-4.150,Z=-2.353,t=-3.601,Z=-3.798; all P＜0.05).However there were no significant differences in esophageal dynamics indexes between patients with lower esophageal leiomyoma accompanied GERD symptoms and without GERD symptoms (all P＞0.05).There were no significant differences in esophageal dynamics indexes between the GERD patients and patients with lower esophageal leiomyoma accompanied GERD symptoms (all P＞0.05).LESRR level of patients with lower esophageal leiomyoma (71.4％(45.5％,150.0％)) increased after endoscopic submcosal dissection (Z=-2.194,P=0.028).Conclusions Lower esophageal leiomyoma may affect esophageal motor function,which contributed to anti-reflux esophageal function decline.Lower esophageal leiomyoma combined with gastroesophageal reflux symptoms are not uncommon.
